5. The outer side surfaces of the two parallel plates in the outer sheet of the collecting pipe are respectively provided with a convex rib, which is the fifth technical characteristic of the utility model. The purpose of this design is: the arrangement of the two convex ribs plays a role in positioning when the outer piece of the collecting pipe and the inner piece of the collecting pipe are buckled with each other, so that the outer piece of the collecting pipe and the inner piece of the collecting pipe can be better welded and spliced.

6. The design that a first strengthening rib is respectively arranged between two parallel plates and a vertical plate in the outer sheet of the collecting pipe is six technical characteristics of the utility model. The purpose of this design is: the intensity of the outer piece of pressure manifold itself can be strengthened in the setting of first strengthening rib to strengthen the holistic intensity of pressure manifold.

The technical scheme is as follows: the utility model provides a pressure manifold for harmonica tubular water-cooling board, includes the pressure manifold body, the pressure manifold body is formed by the mutual lock concatenation of pressure manifold outer plate and pressure manifold inner plate, open on the front of pressure manifold inner plate has a plurality of through-holes, the drill way of through-hole is to inboard turn over the book and is formed with the turn-ups, perhaps the drill way of through-hole is to inboard turn over the book and be formed with the turn-ups.

Compared with the prior art, the utility model, firstly, the collecting pipe used for the harmonica tubular water-cooling plate can increase the contact area of the welding joint of the collecting pipe and the harmonica tube or the flat tube, thereby avoiding the leakage point in the use process of the welding joint of the collecting pipe and the harmonica tube or the flat tube; and secondly, the collecting pipe for the harmonica-shaped water cooling plate has the advantages that the size of the collecting pipe inner sheet in the collecting pipe is large, so that the size of the concave die which can be placed in the groove of the collecting pipe inner sheet is large, the service life of the corresponding concave die is longer, and the production cost of the collecting pipe is reduced.
